MARINE TORPEIDO.

SPECIFICATION forming part of Letters Patent No. 559,711, 'da/ced May 5, 1896.

I Application filed February 21, 1895. Serial No. 539,190. (No model.)

lt well known that in the use of marine i 5 torpedoes, while it is not difficult to bring the torpedo into proximity to the vessel or other object to be destroyed, it is sometimes ditlienit to bring it into contact therewith. Moreover, although in some casesitm-'onld be de so sirable to dela-y the explosion of the torpedo after it has been brought into contact with the vessel, it has' not been possible to hold it against the vessel after it has struck the same.

lt is the object of this invention to provide :z5 atorpedo which shall with certainty be attracted to and held against an iron or steel vessel, and shall also be capable of retaining its contact with the vessel until such time as the operator desires the explosion. To this 3e end the torpedo is'provided with an electro magnetwhieh will attract it to and cause .it

1o be held against the iron or steelvessel, as before stated. V

ln the'accompanying drawings, lfi'gure l is 7,5 n plan view, in ontline,of a torpedo, the position oi' the magnet being indicated by dotted lines. Figi 2 is a plan view of a magnet adapted for the purpose referred to, the inagnel boing pal-Ilybroken ont to show certain 4o features of construction. Fig. 1i is an ond View ol' the magnet.

'lhe torpedo A maybe of any preferred construction, the improvement herein set forth A being independent of ythe form or driving mechanism thereof.' It is assumed to be of 45 'is mounted a powerful magnet B.

The invention herein set forth is not directed to the particular construction of magnet, as any electromagnet of sufiicient power may be employed.. In the construction of magnet shown, which -is merely for the purpose of illustration,- cores C are provided, 55 which are wound with layers of insulated wires D, and E represents disks attached to the cores, and to which are secured pole-pieces F, the latter being shaped to conform to the curvature of the shell of the torpedo.

It will be understood that when the magnet is energized suicient magnetic force or power1 is genrated to attract the torpedo to and hold it against the iron or steel vessel, the contact of the vessel and torpedo being maintained until the ltime of explosion.

Ve claim as our inventioni.

The combination with a torpedo-shell of an eleetrolnagnet 'mounted within the shell and at the bow thereof,su"ch magnet having curved 7o pole-pieces conforming to the converginglines et' the shell whereby the torpedo may be attracted'to and held aga-inst the hull of an iron er steel vessel.v

In testimony whereot` we have signed our 7 5 naines .to this specification in the presence of two snbscribir. g witnesses.
